To estimate the price of the 2016 Porsche Cayenne GTS V6 3.6L GTS (Mid+), I first looked at the selling prices of similar cars. The closest match is the 2015 Porsche Cayenne GTS V6 3.6L Twin Turbo with 138000 km, which sold for 110000 SAR on 2024-04-19. Given that the car in question has higher mileage (269700 km) and is in average condition, I adjusted the price downwards. Another relevant data point is the 2014 Porsche Cayenne V6 3.6L Turbocharged with 127000 km, which sold for 76500 SAR on 2023-10-18. Considering the age and mileage difference, I further adjusted the price. I also reviewed listed prices for similar cars, such as the 2016 Porsche Cayenne GTS V6 3.6L Twin Turbo with 163000 km listed for 129500 SAR, and the 2016 Porsche Cayenne GTS V6 3.6L with 140000 km listed for 150000 SAR. These listings are higher than the selling prices, so I used them as upper bounds. Factoring in the higher mileage and average condition of the car in question, I arrived at a final estimate.
